Exploring Salt Crystals

Exploring Salt Crystals | Science Fair Projects | STEM Projects
Have you ever wondered how salt crystals form? In this project, you'll explore how adding different ingredients to a salt solution can affect the size of the salt crystals.


The hypothesis is that when more ammonia is used, more salt crystals are formed.

Method & Materials

You will create four salt solutions with different ingredients, place a sponge in each bowl, and observe the size of the salt crystals that form.
You will need five bowls, four sponges, one packet of salt, one bottle of bluing liquid, one bottle of ammonia, one tablespoon, and one caliper.


The results showed that the solutions with only salt, water, and bluing had little crystallization, while the solutions with ammonia had more crystallization. The more ammonia added, the more crystallization occurred, with the solution with the most ammonia having the highest crystal height of 8.2mm.

Why do this project?

This science project is interesting because it explores how adding different ingredients to a salt solution can affect the size of the salt crystals.

Also Consider

Experiment variations include using sugar to form the crystals and using seawater.
